Some one plzs help with this question peter weighs 105 kg he wants to lose 500 grams per week how many weeks will it take for him to have a mass of 90 kg

30weeks

Step-by-step explanation:

From the question given,

Peter's weight = 105kg

Now, Peter wants to lose 500g per week i.e

Peter wishes to lose = 500/1000 = 0.5kg per week.

The mass losed by Peter = 105 —90 = 15kg

Now if Peter losed 0.5kg in 1week, then he will lose 15kg in = 15/0.5 = 30weeks

Therefore, it will take Peter 30 weeks to have a mass of 90kg
